A tube of length 50 cm is containing a gas in two sections separated by a mercury column of length 5 cm as shown in figure. The open end of tube is just inside the Hg surface in container find pressure difference of gases in two sections. [Assume atmospheric pressure 75 cm of Hg column]

pressure=h*d*g
 
As in the lower section height of mercury is not raised pressure in lower section=P_{atm} =75cm of Hg
 
As in the upper section height of mercury raised by 10cm pressure=75-10=65mm of Hg
